 APPENDIX C 
 PHS FLOWTHROUGH TERMS 
  
 1. Government Reserved Rights. 
  
 1.1 Reserved License Rights. KSA agrees that PHS has reserved on behalf of the Government of the United States of America (the
Government) an irrevocable, nonexclusive, nontransferable, royalty-free license for the practice of all inventions licensed under the Licensed Patent Rights throughout the world by or on behalf of the Government and on behalf of
any foreign government or international organization pursuant to any existing or future treaty or agreement to which the Government is a signatory. 
  
 1.2 Cooperative Research and Development Agreement Rights. In the event that Licensed Patent Rights are Subject Inventions made under a Cooperative
Research and Development Agreement (CRADA), KSA grants to the Government, pursuant to 15 U.S.C. /3710a(b)(l)(A), a nonexclusive, nontransferable, irrevocable, paid-up license to practice Licensed Patent Rights or have Licensed Patent Rights
practiced throughout the world by or on behalf of the Government. In the exercise of such license, the Government will not publicly disclose trade secrets or commercial or financial information that is privileged or confidential within the meaning
of 5 U.S.C. /552(b)(4) or which would be considered as such if it had been obtained from a non-Federal party. Prior to the First Commercial Sale, KSA agrees to provide PHS reasonable quantities of Licensed Products or materials made through the
Licensed Processes for PHS research use. PHS shall assume liability for its research use of the Licensed Products. 
  
 2. Manufacture in United States. KSA agrees that products used or sold in the United States embodying Licensed Products or produced through use of Licensed
Processes will be manufactured substantially in the United States, unless a written waiver is obtained in advance from PHS. PHS agrees that the waiver KSA requested and received for the Existing Agreement (see Attachment One) shall also apply to
this Agreement. 
  
 3. Future Cooperative Research and Development
Agreements. KSA acknowledges that PHS may enter not future Cooperative Research and Development Agreements (CRADAs) under the Federal Technology Transfer Act of 1986 that relate to the subject matter of this Agreement. KSA agrees not to
unreasonably deny requests for a research License from such future collaborators with PHS when acquiring such rights is necessary in order to make a Cooperative Research and Development Agreement (CRADA) project feasible. KSA may request an
opportunity to join as a party to the proposed Cooperative Research and Development Agreement (CRADA). 
  
 4. Research Licenses. 
  
 4.1 Grant of Research License. In addition to the reserved license of Paragraph 3 above in this Appendix C, PHS reserves the right to grant nonexclusive Research Licenses directly or to require KSA to grant nonexclusive Research
Licenses on reasonable terms. The purpose of this Research License is to encourage basic research, whether conducted at an academic or corporate facility, but in no event shall the Research License be used for any 

  









 
commercial purpose. Additionally and in order to safeguard the Licensed Patent Rights, however, PHS will consult with KSA before granting to commercial
entities a Research License or providing to them research samples of materials made through the Licensed Processes. 
  
 4.2 Required Research Licenses. In exceptional circumstances, and in the event that Licensed Patent Rights are Subject Inventions made under a
Cooperative Research and Development Agreement (CRADA), the government, pursuant to 15 U.S.C. /3710a(b)(1)(B), retains the right to require KSA to grant to a responsible applicant a nonexclusive, partially exclusive, or exclusive sublicense to use
Licensed Patent Rights in KSA’s field of use on terms that are reasonable under the circumstances; or if KSA fails to grant such a license, the Government retains the right to grant the license itself. The exercise of such rights by the
Government will only be in exceptional circumstances and only if the Government determines (i) the action is necessary to meet health or safety needs that are not reasonably satisfied by KSA; (ii) the action is necessary to meet requirements for
public use specified by Federal regulations, and such requirements are not reasonably satisfied by the KSA; or (iii) KSA has failed to comply with an agreement containing provisions described in 15 U.S.C. /3710a(c)(4)(B). The determination made by
the Government under this Article is subject to administrative appeal and judicial review under 35 U.S.C. /203(2). 
  
 5. Recordkeeping and Audits. KSA agrees to keep accurate and correct records of Licensed Products made, used, or sold and Licensed Processes practiced under
this Agreement appropriate to determine the amount of royalties due AH. Such records shall be retained for at least five (5) years following a given reporting periods. They shall be available during normal business hours at KSA s premises for
inspection at the expense of PHS by an accountant or other designated auditor selected by PHS for the sole purpose of verifying reports and payments hereunder. The accountant or auditor shall only disclose to PHS information relating to the accuracy
of reports and payments made under this Agreement. If an inspection shows an under reporting or underpayment in excess of five (5%) percent for any twelve (12) month period, then KSA shall pays the unreported Royalties, including any late charges as
required by Section 4.5 of this Agreement. All payments required under this Section shall be due within thirty (30) days of the date PHS provides KSA notice of the payment due. 
  
 6. Efforts to Commercialize. KSA shall use its reasonable best efforts to introduce the Licensed Products into the commercial
market or apply the Licensed Processes to commercial use as soon as practicable. Reasonable best efforts for the purpose of this provision shall include, but not be limited to, adherence to the Commercial Development Plan. The efforts of a
sublicensee shall be considered the efforts of KSA. 
  
 7. Efforts to Make
Available to Public. Upon First Commercial Sale, until the expiration of this Agreement, KSA shall use the reasonable best efforts to keep Licensed Products and Licensed Processes reasonably accessible to the public in the Licensed
Territory. 
  
 8. Indemnification by KSA. KSA will indemnify, as of
the effective date of this Agreement, and hold PHS and AH, their employees, students, fellows, agents, and consultants harmless from and against all liability, demands, damages, expenses, and losses, including but not limited to death, personal
injury, illness, or property damage in connection with or arising out of: a) the use by or on behalf of KSA, its sublicensees, directors, employees, or third parties of 

  









 
any Licensed Patent Rights; or b) the design, manufacture, distribution, or use of any Licensed Products, Licensed Processes or materials by KSA, or other
products or processes developed in connection with or arising out of the Licensed Patent Rights. KSA agrees to maintain a liability insurance program consistent with sound business practice. 
  
 9. Required Sublicenses. When the public health and safety so require, and
after written notice to KSA providing KSA a sixty (60) day opportunity to respond, PHS will have the right to require KSA to grant sublicenses to responsible applicants, on reasonable terms, in any Licensed Fields of Use under the Licensed Patent
Rights, unless KSA can reasonably demonstrate that the granting of the sublicense would not materially increase the availability to the public of the subject matter of the Licensed Patent Rights. PHS will not require the granting of a sublicense
unless the responsible applicant has first negotiated in good faith with KSA. 
  
 10. Termination. PHS reserves the right according to 35 U.S.C. /209(f)(4) to terminate or modify this Agreement if it is determined that such action is necessary to meet requirements for public use specified by federal
regulations issued after the date of the license and such requirements are not reasonably satisfied by KSA. 
  
 11. Appeal of Termination. Within thirty (30) days of receipt of written notice of PHS unilateral decision to modify or terminate this Agreement, KSA may, consistent with the provisions of 37 CFR Part
404.11, appeal the decision by written submission to the designated PHS official. The decision of the designated PHS official will be the final agency decision. KSA may thereafter exercise any and all administrative or judicial remedies that may be
available. 
  
 12. Final Report. Within ninety (90) days of
expiration or termination of this Agreement, a final report will be submitted by KSA to AH and PHS. Any royalty payments, including those incurred but not yet paid (such as the full minimum annual royalty), and those related to patent expense, due
to AH will become immediately due and payable upon termination or expiration. If terminated under Section 8 of the Agreement, sublicensees may elect to convert their sublicenses to direct licenses with PHS pursuant to Paragraph 4.03 of the
Chloroquine License. Unless otherwise specifically provided for under this Agreement, upon termination or expiration of this Agreement, KSA will return all Licensed Product(s) or other materials included within the Licensed Patent Rights to AH or

 APPENDIX E 
  

COMMERCIAL DEVELOPMENT PLAN 
  
 RESEARCH, DEVELOPMENT AND MARKETING PLAN 
 “Methods of Protecting Vasculature From Damage by Diphtheria Toxin and Pseudomonas 
 Toxin-based Immunotoxins During Therapy: Vascular Protection by Chloroquine During Brain 
 Tumor Therapy with Tf-CRM107/NC
66000” 
  
 May 28, 2002 
  
 DEVELOPMENT PLAN 
  
 CLINICAL REGULATORY 
  
 The above referenced technology will be used to reduce the neurotoxicity of the immunotoxin, Tf-CRM107 (also known as NC 66000). Animal Studies carried out by Dr. Richard
Youle (NIH) indicate that Chloroquine (an anti-malaria drug) increases the maximum tolerated dose of NC 66000 by 50%. 
  
 NC 66000 is a therapy that is currently directed at a specific niche; brain cancer patients. The clinical trials for Chloroquine/NC 66000 will also be directed to this
niche and will be conducted at a limited number of sites (approximately 10 to 15), to ensure that the neurosurgeons are well trained in the procedure and to ensure that safety issues can be evaluated and proper follow-up care is provided to
patients. These sites will most likely be the same sites where previous clinical trials for NC 66000 were conducted. Clinical Trials will begin with a single centre Phase I trial in the first half of 2003. These studies will establish the maximum
tolerated dose as well as Chloroquine’s safety profile when used in conjunction with NC 66000 therapy. Subject to regulatory and IRB approvals, a multicentre Phase 11 Clinical Trial is projected to begin the second half of 2004. A Phase III
Clinical Trial will follow beginning in the second half of 2006. It is expected that a BLA will be submitted during the second half of 2008. 
  
 MANUFACTURING 
  
 KS Avicenna, will be responsible for all activities associated with the manufacture of NC 66000 for the human clinical trials with Chloroquine. KS Avicenna will complete the final stages of manufacture of NC 66000 in
the second half of 2002 for use in the Phase I Chloroquine/NC 66000 Clinical Trial. 
  
 SALES PLAN 
  
 Once marketing approval is received for the use of
Chloroquine as an adjunct with NC 66000, the drug will be provided to hospitals that are familiar with the NC 66000 therapy. These will be hospitals where NC 66000 is currently in use. This ensures that procedures are followed and safety can be
evaluated. At peak penetration, it is expected that over 100 leading neuro-oncology centers and hospitals in the US will gain access to the NC 66000 technology. 
  










 Given the relatively small number of sites (when compared to other biopharmaceuticals), marketing efforts will be managed
by a direct sales force employed by KS Avicenna. In addition to the direct sales force, presentations at conferences, both academic/professional and industrial, such as the AANS (American Association of Neurological Surgeons) and publications in
academic and industrial journals including the internet will ensure that neurosurgeons and oncologists are aware of the Chloroquine/NC 66000 combination therapy and its benefits. 
  
 MARKET ANALYSIS 
  
 The clinical development of NC 66000 is focused on recurrent, inoperable, high grade glioma patients. The category of high-grade glioma (HGG) is defined to include
Glioblastoma Multiforme (GBM) and Anaplastic Astrocytoma (AA). According to estimates found in Future Oncology V3 (7/8), GBM and AA account for 41.8% and 5.9% of the total incidence of primary brain cancer, respectively. Patients with malignant
gliomas typically undergo surgery, radiation or chemotherapy in an attempt to prolong survival, but in almost all of them the gliomas will recur, which is also why this diagnosis is nearly uniformly fatal. Therefore, we assume that the incidence of
recurrent HGG is the same as the incidence of original HGG. To determine the number of inoperable tumors, we estimate that 65% of recurrent, high grade gliomas are inoperable. This estimate is based on discussions with neurosurgeons. 
  
 The incidences for high grade glioma (HGG) in the United States and Canada have been
extrapolated from 1997 estimates at an incidence of 20,000 using 1.17 % as the calculated annual increase in primary brain cancer incidence. (Future Oncology V3 (7/8), 1998). These calculations are used to obtain the total market size in patients
for this market segment. 
  
 The estimated projections for the market penetration
for immunotoxins and market share for the NC 66000 product are indicated in Table 2 below. NC 66000 sales will begin in 2005. As the first immunotoxin to market, NC 66000’s impressive efficacy will drive adoption to high levels. The penetration
rate for immunotoxins will increase to a peak penetration of 65% in 2010 to 2012 as physicians and clinical centres realize the benefits of this type of therapy. Market share projections assume that NC 66000 will be the first to the market and will
have two years of market exclusivity in years 2005 and 2006. Original estimates for market share projected that NC 66000 would maintain a leading market share until 2010 as first to the market for an unmet clinical need, would give NC 66000 a
significant advantage. 
  
 With the approval of the use of Chloroquine as an
adjunct to NC 66000 therapy by late 2008 or early 2009, NC 66000 will extend its position as a leader in the recurrent non-operable brain tumor market until 2014. The net effect of the use of Chloroquine will be to increase the number of patients
that could benefit from NC 66000 therapy thereby increasing NC 66000’s market share and net sales. Table 3 demonstrates the projected increase in market share and sales of NC 66000 that could occur with the use of Chloroquine. Use of
Chloroquine as an adjunct will increase the cumulative sales of NC-66000 by at least $58 million. 
  
 The improved safety profile of NC 66000 with Chloroquine will further expand the treatment population that may benefit from this novel therapy. Thus, in addition to non-operable recurrent HGG, the use of Chloroquine
may expand the use of NC 66000 to include operable tumors, 

  









 
lower grade gliomas and pediatric tumors. The increased sales projections in Table 3 are therefore very conservative and could be significantly higher.

  
 Sales projection estimates are calculated from assumptions about pricing over
the life of the product as well as the estimate that the average number of treatments per patient is 2.
